All you have to do is plug in 1/2 where the z is so you would end up with 12+1/2 which equals 12 1/2

Solve for x. *<br> 52°<br> (6x + 2)°
pickupchik [31]

Answer:

x=21

Step-by-step explanation:

The two angles form a straight line so they add to 180

6x+2+52 = 180

6x+54= 180

Subtract 54 from each side

6x+54-54 = 180-54

6x= 126

Divide by 6

6x/6 =126/6

x = 21

Is the ordered pair a solution of y ≥ 2x − 5? a. (3, 1) b. (1, −4)
Deffense [45]

Answer:

a. Yes

b. No

Step-by-step explanation:

To find if an ordered pair is a solution to the inequality, substitute its x and y values for the x and y in the inequality and solve. If the equation is true, then it is a solution. If it is not, then it is not a solution.

1) First, substitute the x and y values of (3, 1) into the inequality. So, substitute 3 for x and 1 for y:

1 \geq 2(3)-5\\1\geq 6-5\\1\geq 1

1 is greater than or equal to 1, so (3,1) is a solution.

2) Second, do the same with the point (1, -4). Substitute 1 for x and -4 for y:

-4\geq 2(1)-5\\\\-4\geq 2-5\\-4\geq -3

However, -4 is not greater than or equal to -3, thus (1, -4) is not a solution.
